I've noticed the police have no uniformity to their bikes? Are they supplying their own using a department stipend or just buying their own. I would have thought the city would maintain a fleet just like they do with cars.

I wonder if the police being on bikes changes the interaction between protesters and the police at all? Cops I spoke to in Louisville said being on bikes made them more approachable, especially with kids and young people. I didn't have a chance to really follow the Nato protests but I hope they weren't a repeat of the Occupy Oakland protests, which seemed quite a police over-response.
